Abstract: 798,203. Stuffing-box substitutes. BAKER PERKINS, Ltd. May 16, 1956 [May 16, 1955], No. 15219/56. Class 122 (5). The shaft 12 of a mixing machine, particularly a dough mixing machine, is sealed where it passes through the mixing chamber wall 10 by a gland G axially movable on the shaft by pivotal lever means so that it may be either held in sealing engagement with the shaft opening 11, as in Fig. 1, or spaced therefrom, as in Fig. 4, to provide access for inspection and cleaning. A gland plate 19 is shouldered at 20 to fit the shaft opening 11, and in the working position of the gland shown in Fig. 1 is urged into sealing contact with the wall 10, through a neoprene gasket 21, by a spring 24 compressed between a rotatable ring 23 sealed to the shaft by packing 23a and pressed into end face sealing contact with a ring 22 fixed to the plate 19 and a collar 25 having a key 25a slidable in a keyway 26 in the rotatable shaft 12 and held in a yoke ring 27. Pins 28 secured to the ring 27 engage slots 29 in arms 30a of a bell-crank lever 30 pivoted on a fixed trunnion 32. The pins 28 also extend through elongated slots 34 in straps 33 secured to the plate 19. A toggle link 44 is pivotally connected at 46 to the arm 30b of the crank lever 30 and at 45 to one arm 41b of a bell-crank 41 pivoted at 43 and pivotally connected by its other arm 41a to a control bar 38. To move the gland from the normal position shown in Fig. 1 to the cleaning position shown in Fig. 4, the bar 38 is pushed inwardly by handle 39, i.e. to the left in Fig. 4, and the lost motion between pins 28 and slots 34 provides a jerk to overcome any sticking of the plate 19 in the opening 11. To return the gland, the bar 38 is pulled outwardly until the bell-crank 41 meets a stop pin 47, the linkage being arranged such that the link 44 has then just passed over-centre with respect to pivots 43 and 45 and the mechanism is thereby locked in position with the gland plate 19 in sealing contact with the wall 10.
